Title: Improvements relating to casings for explosives
IPC: F42B33/02
Filed: 1956-11-19
Abstract: 787,832. Ammunition projectiles and land mines. AKTIEBOLAGET BOFORS. Nov. 19, 1956 [Jan. 11, 1956], No. 35284/56. Classes 9(1) and 9(2) The casing for a mine or projectile is formed in a two-part mould 1, 2 from an explosive reinforced with a fabric layer 7, e.g. glass wool. The upper half 1 of the mould has an opening 3 in which is inserted a sleeve 4 for holding the ignition mechanism, so that the sleeve is cast in the casing, and filling plugs 5, 6 are screwed into the mould. The mould is lined with the layer 7, which is of material undetectable by mine detectors, and explosive, which can be cast, is then poured in through the plug hole 6 or opening 3. When sufficient explosive has solidified to give a casing of the required thickness, the surplus explosive is poured out, the process may be repeated and with a different explosive to produce a casing having an outer reinforced layer and inner layers as required. The casing is then removed and filled. T.N.T. , tritonal, torpex and cyclotol may be used to form the casing. The projectile mould, Fig. 4, has openings 3<SP>1</SP>, 5<SP>1</SP> at top and bottom to receive sleeves 4<SP>1</SP>, 6<SP>1</SP> embedded in the explosive during the casting and intended to house the ignition mechanism. The layer 7<SP>1</SP> may be of glass wool or metal. Through sleeve 4<SP>1</SP> is inserted a tube 9 having one or more openings at the bottom and rotatably connected to a container (not shown) of molten explosive. Explosive passing through the rotating tube flows through the openings and is thrown by centrifugal force against the lay 7<SP>1</SP>. The tube is slowly raised as the coating is formed. The process may be repeated with the same or a different explosive and the mould may also be rotated to distribute explosive on the layer 7<SP>1</SP>.

A predetermining counter furnished with stop mechanism comprises manually-operable means for individually rotating the number wheels for pre-setting them, and manually-operable means for rotating the number wheels simultaneously to reset them to their pre-set positions. The counter is described as applied to a textile drawing frame. The casing 1, Fig. 1, includes a hank counter 2 the numeral wheels of which are mounted on a shaft 26, Fig. 3, and a predetermining counter 3 the numeral wheels of which are mounted on a shaft 21. Extending parallel with the shafts 21, 26 is a shaft 11 which supports a pair of arms 6 carrying four rollers 7, Fig. 2, each of which rests on the periphery of a cam 8 integral with the associated numeral wheel of the counter 3. One of the arms 6 has a pin and slot connection with a latch 9, Fig. 3, to which it is also connected by a spring 10. The latch 9 normally holds a bellcrank lever 13, 14 in the position in which it keeps a micro-switch 15 closed. The switch 15 being in the circuit of the drive of the machine with which the counter is associated. When each roller 7 moves into a notch 9<SP>1</SP> in its associated cam 8 the arms 6 move clockwise and the latch 9 is moved to release the bellcrank 14 which is moved by a spring, not shown, to open the micro-switch 15. A lug on the bell-crank 13, 14 moves a pawl 18 against the pressure of a spring 23 so that its outer end leaves a slot 19 in a cam 20 fixed to the shaft 21. The shaft 21 may then be rotated by the knob 22 for a revolution to reset the counter 3 to its pre-set position. Pre-setting. Each numeral wheel has an associated gear 37, Fig. 5, and the shaft 11 carries a gear adjacent thereto. Depression of a button 34, 38, 39, 40, Fig. 1, brings a pinion 35, Fig. 2, into mesh with the corresponding gear 37 and its adjacent gear on the shaft 11 so that rotation of the shaft 11 by the knob 29 effects movement of the selected wheel 37 and a slot 46 in its hub picks up a spring- pressed pawl 47 on the associated numeral wheel which is thereby moved relatively to its shaft 21. The gear 37 carries two pawls 44 which normally couple the gear to a ratchet 42 keyed to the shaft 21. The shaft 26, Fig. 3, is normally locked by a bar 25 which has a V-shaped notch which engages a corresponding cam disc 27 of the shaft 26. A pawl 30 pivoted at 31 and connected to the bar 25 normally locks a cam 32 on the shaft 11. When it is desired to set the numeral wheels of the predetermining counter a key is inserted in the lock 41, Fig. 1, and operated to effect movement of the bar 25 to the left to free the shafts 11 and 26. Specification 721,383 is referred to.
